Answer:
a) The industry is divided into four sectors: primary, secondary, tertiary and quaternary. Of the industries named in the report, we can identify:
- primary - farming, mining, lumbering (since they are associated with collecting the raw materials)
- secondary - construction (involved in the production of a good using raw materials)
- tertiary - banking, warehousing, transportation (providing services)
- quaternary - telecommunication
b) The report listed the construction industry (making roads, dams...) as the secondary industry. Industries in this sector transform raw materials into goods or are simply involved in construction, which is a special kind of finished good (infrastructure).
It is often divided into light and heavy industry. Light industry requires less capital for equipment, and makes goods primarily for the end user (for example, FMCG industries), while the heavy industry involves big plants and facilities and complicated industry processes.
